CY3655 Hardware User Guide
USB Port
The USB type-B connector allows a USB connection to a PC. The power pin of the connector
goes to a jumper (J5) labeled “VBUS PWR” to allow USB power to be disconnected from the
system for emulator based development. In addition the USB signals can be viewed with an
oscilloscope or logic analyzer at header J7. For best USB signal quality, remove the jumpers
on J8 and J9 that connect the PS/2 port.
PS/2 Port
The PS/2 connector allows a PS/2 connection to a PC using the supplied cable. The power
pin of the connector goes to a jumper (J13) labeled “PS/2 PWR” to allow PS/2 power to be
disconnected from the system for emulator based development. In addition the PS/2 signals
can be viewed with an oscilloscope or logic analyzer at header J7. The enCoRe II pins used
for PS/2 are normally P1.0 and P1.1, but the alternate pins P1.5 and P1.6 can be used by
moving the jumpers on J8 and J9 to the side labeled “ALT PS/2”.
Analyzer Headers
P1, P2, and P3 are 20-pin headers that are compatible with Agilent logic analyzer terminator
adapters. This feature allows for a quick and simple debugging connection.
Prototyping Area
An area on the board is available for user-customized prototyping. The through-hole area
contains 0.1” spaced holes appropriate for DIP devices. On each side of the through-hole area
there is a ground row and a power row. Each power row can be individually configured to use
either the board’s VCC or the VREG output from the enCoRe II. There is also a surface mount
prototype area that accepts either 0.050” pitch parts or 0.025” pitch parts. Holes on the
outside of the surface mount pads allow signals to easily be soldered from elsewhere on the
board. A single row of signals above the proto area allows enCoRe II signals to be wired to
the proto area. This row has all signal names in silkscreen by their respective holes on both
the top and bottom side of the board.
